How do I prepare my construction business for tax season?
Tax season for construction businesses is either straightforward or chaotic depending on what you did throughout the year. If your books are current and organized, preparation is mainly gathering documents. If things got away from you, catching up now beats scrambling in April.
Start by reconciling your bank and credit card accounts through December. Every transaction should be categorized correctly. This is where most problems surface. Duplicate entries, missing deposits, expenses coded to the wrong job. Finding errors now gives you time to fix them before your accountant starts working on your return.
Review your job costing reports. Each completed project should show materials, labor, and subcontractor costs assigned to it. Accurate job costing isn’t just for taxes. It tells you which types of work actually made money. If you can’t pull a profitability report by job, your books need cleanup before tax prep can start. A bookkeeper near Gentry who understands construction can help get this sorted quickly.
Gather documentation for every deduction you plan to claim. Receipts for equipment, tools, materials, insurance premiums, licensing fees, and any other business expenses. The IRS requires records that show the amount, date, and business purpose. A bank statement alone doesn’t prove a $400 charge at Home Depot was for a job and not a personal deck project.
Issue 1099s to subcontractors by January 31. You need to send 1099-NEC forms to anyone you paid $600 or more who isn’t incorporated. This catches a lot of contractors off guard because it requires having W-9s on file with correct addresses and tax IDs. Start tracking down missing W-9s now if you haven’t already. Late 1099s mean penalties.
Review equipment purchases for depreciation decisions. Large equipment and vehicles can be depreciated over time or deducted immediately under Section 179. The right choice depends on your tax situation this year versus future years. Your accountant needs a complete list of what you bought, when, and how much you paid.
Verify your mileage records if you’re claiming vehicle deductions. The IRS is particular about mileage documentation. Reconstructing a year of business trips from memory doesn’t work. If you haven’t been tracking mileage, use calendar entries, job schedules, or any other records to estimate business miles as accurately as possible.
Check for commonly missed deductions. Safety equipment, bond premiums, job site rentals, licensing and continuing education, home office if you qualify. Construction contractors leave money on the table because they forget about smaller expenses that add up over the year.
Get your books to your accountant early. Waiting until the last minute limits your options for tax planning and means your return gets rushed. Clean, accurate records make for a smooth handoff to your CPA instead of weeks of back-and-forth sorting through messy records.
The real key is monthly bookkeeping throughout the year. When transactions are categorized as they happen, receipts are saved, and accounts are reconciled monthly, preparing for taxes is just running reports. The chaos happens when twelve months of bookkeeping gets crammed into a few weeks.
